Spin Newbie Question

Tim Creed

As a newbie to the Prop, I have what I'm sure is a simple question. I'm in a repeat loop with a WHILE conditional statement that exits the loop upon a specific pin input state. It then goes into a second conditional repeat loop that (at some point) I want to exit and return to the first loop. How do I get back to the first loop? Something like a JUMP command in assembly language.

QUIT?

The way that you have described it it looks to me like:

repeat
   bla bla
   bla bla
while somecondition

repeat someothercondition
   bla bla
   bla bla

Now when the second loop exits you want to start at the first. You could just add another repeat loop around the whole thing:

repeat
    repeat
        bla bla
        bla bla
    while somecondition

    repeat someothercondition
        bla bla
        bla bla

Do I have the right picture in mind ?

Be careful with the indentation.

Sure, simple enough. I was thinking more along the lines of calling subroutines, but a nested repeat should do the trick. Thanks for the suggestion.

I tend to get my indentation in a mess if it's more than a couple of levels deep so generally end up splitting the code into separate methods, something like:

PUB
  repeat
     a_method
     another_method

PRI a_method
    repeat
        bla bla
        bla bla
    while somecondition


PRI another_method
    repeat someothercondition
        bla bla
        bla bla

Probably a bit slower in execution though.

By the way, welcome to the wonderful world of propelling!

Thanks, I'm really enjoying it so far. Spin is an easy shift from an AV control system that I've been programming for years. I've been using SX chips occasionally, programming in assembly. The Props architecture sure beats the heck out of dealing with interrupts.
